How does the ultrasonic homogenizer work?

How does a ultrasonic homogenizer work? The ultrasonic electronic generator transforms AC line power to a 20KHz (Standard, other frequency optional) signal that drives a piezoelectric convertor/transducer. This electrical signal is converted by the transducer to a mechanical vibration due to the characteristics of the internal piezoelectric crystals.

La vibración se amplifica y se transmite a lo largo del cuerno/sonda donde la punta se expande y contrae longitudinalmente. La distancia que recorre la punta depende de la amplitud seleccionada por el usuario a través del control de amplitud. En líquido, la rápida vibración de la punta provoca cavitación, la formación y colapso violento de burbujas microscópicas. El colapso de miles de burbujas de cavitación libera una tremenda energía en el campo de cavitación. Los objetos y superficies dentro del campo de cavitación son "procesados".

The probe tip diameter dictates the amount of sample that can be effectively processed. Smaller tip diameters (Microtip probes) deliver high intensity sonication but the energy is focused within a small, concentrated area. Larger tip diameters can process larger volumes.

The choices of a generator and horns/probes are matched to the volume, viscosity and other parameters of the particular application. Please consult with a Sonicator product specialist for help with selecting the proper model and accessory for your application.
